You already have a basic understanding of the GarageBand window, and you have some experience working with tracks. Now it’s
time to dive in and start filling those tracks with custom music that you create with Software Instruments.

In this lesson, you are going to learn editing and recording techniques for building music with Software Instrument regions.
You’ll also learn how to change the tempo, record your own beats, and split, join, and change instruments for Software Instrument
tracks in the Timeline.

Preparing the Project

Let’s take a moment to open and save the first project for this lesson before moving on to the main exercises.

This project shows the complete workflow of a recorded Software Instrument region starting with the original recording in
the top track. The Joined Final Piece track shows the finished edited version of the recording. You’ll work on editing this
project shortly. But first, this is a good time to learn how to monitor the processor with the playhead because this project
may be demanding on your computer.
